Just to clarify, you were hitting buttons on the radio right? Anti-lock brake system should not have done that, especially considering it produced feedback followed by a ringing noise. The ringing could just be you, the feedback, depending on the DB's, could have caused temporary ringing.
How is the weather over there? Raining hard by any chance? Spill any drinks in there before work?
its a touch screen
pretty sure I only hit radio buttons..majority of them are radio buttons...anytime Id touch the buttons Id get zapped with hearing -1 effects...or the volume control on the steering wheel.
yeah I suppose its been raining. No spills...though there was a recall on my car for windshield wipers..I guess if it rains they've been known to cause an electrical shortage..they told me to wait for a letter in the mail if it affected me I guess.
